But that's what I don't understand. Which python file? We spark submit one file called ctr_parsing.py, but it only has 150 lines. So what is MapPartitions at PythonRDD.scala:374 referring to? ctr_parsing.py imports a number of support functions we wrote, but how do we know which python file to look at? Furthermore, what on earth is null:-1 referring to?
